    摘要: The present invention is directed to enzymes and intermediates of the non-mevalonate isoprenoid pathway downstream of 2C-methyl-D-erythritol 2,4-cyclopyrophosphate and upstream of isopentenyl pyrophosphate or dimethylallyl pyrophosphate. These are used as a basis for a screening method for inhibitors of these enzymes, and a method for identifying inhibitor-resistant variants thereof. Further disclosures refer to DNA coding for said enzymes and for inhibitor-resistant variants thereof, vectors containing said DNA, cells containing said vector, and plant seeds comprising cells containing said vector. This invention is useful for the inhibition of the biosynthesis of isoprenoids in plants, bacteria and protozoa, for confering herbicide-resistance to plants, as well as for weed control in agriculture using a crop containing a herbicide-resistant gene and an effective amount of a suitable herbicide.

    摘要: A method is described for screening for the presence or absence of inhibition of 6,7-dimethyl-8-ribityllumazine synthase activity comprising the following steps : (a) preparing a first aqueous mixture containing a protein having a plant-type 6,7-dimethyl-8-ribityllumazine synthase sequence, 5-amino-6-ribitylamino-2,4(1H,3H)pyrimidine-dione and 3,4-dihydroxy-2-butanone 4-phosphate; (b) reacting said first mixture during a predetermined period of time at a predetermined temperature and subsequently detecting the level of 6,7-dimethyl-8-ribityllumazine; (c) preparing a second aqueous mixture by including in said first mixture a predetermined amount of a chemical test sample; (d) reacting said second mixture during the predetermined period of time at the predetermined temperature and subsequently detecting the level of 6,7-dimethyl-8-ribityllumazine; (e) determining the presence of inhibition of 6,7-dimethyl-8-ribityllumazine synthase by observation of whether the level detected in step (d) is lower than the level detected in step (b).
